The NHS makes widespread use of independent contractors providing essentially "privatised" services. Examples are dentists, opticians, and, most widely used of all, General Practitioners.
The current NHS model is unsustainable and no other country uses anything like it. It was fine seventy years ago when the population of the UK was about two thirds what it is today, when the service only provided essential and basic services and when people were lucky to live a year or two after retirement.
It is no longer sustainable. People who are poor (and those who are not) already have difficulty accessing healthcare: they wait weeks for GP appointments, spend hours if they are unfortunate enough to need A&E, wait months or even years for hospital treatment and suffer pain and discomfort in the process. The NHS is not the envy of the world and it is doubtful that it ever was. If it was so good other nations would have copied it and none has.
Piling ever-increasing sums of taxpayers' cash into it is not the answer. It does not work and needs radical overhaul. If that means making more use of private contractors then so be it. It is stupid to cry "the end of the NHS" every time changes are proposed.
